Note 1: Composition of Authorization Code, and its relation to Check Sum (related to INDEX 12~14).
	Authorization Code consists of D0 D1 D2 D3 D4 D5 D6.
					Seek Digits				Check Digits

(When using Check Sum, a maximum of seven digits, including Check Digits, are available.) There is a maximum of two Check Digits and eight Seek Digits.

•D5 is determined by Check Sum-1 and Check Code-1.

MOD10 (b4 ⋅ D0 + b3 ⋅ D1 + b2 ⋅ D2 + b1 ⋅ D3 + b0 ⋅ D4 + D5) = Check Code-1

•D6 is determined by Check Sum-2 and Check Code-2.

MOD10 (b4 ⋅ D0 + b3 ⋅ D1 + b2 ⋅ D2 + b1 ⋅ D3 + b0 ⋅ D4 + D6) = Check Code-2

Note 2: Only eight digits will print out on SMDR in the case of EPN – Authorization Code. Therefore, checks on authorization codes should be limited to a total of eight digits.
